Affiliate Link Tracking
Your site can record a click; only the program can determine commission credit under its rules.
Two measurements
Outbound clicks and merchant attribution are different.
Campaign labels
Use allowed sub-IDs to identify sources.
Privacy
Do not put personal information in tracking URLs.
Use the data
Compare traffic, click-through and merchant conversions.
Practical rule: Build one clear audience → offer → traffic → conversion path before adding complexity. For a commercial example, see our Jonathan Montoya review.
